52271.以煤制油为燃料的柴油车道路颗粒排放物
[汽车制造业] [2014-03-19]
Particle emissions of a diesel car fueled with coal to liquids (CTL) on road were tested.The particle number and size distribution were mainly studied.Three typical roads were adopted in this test, including urban arterial roads, secondary roads and freeways.The results show that transient particle number of the car has a corresponding relationship with the vehicle speed.With the speed increasing, the number of both nucleation mode particles and accumulation mode particles increase continuously.

52272.使用随机参数二元有序概率单位模型对居民汽车与摩托车拥有量的分析
[汽车制造业] [2014-03-19]
This paper investigates the factors that affect household automobile and motorcycle ownership in large metropolitan areas. Extensive geocoded trip data from Athens, Greece, were modeled with the random parameters bivariate ordered probit model. The study's results indicate that vehicle (automobile and motorcycle) ownership is determined by a number of factors, such as traveler characteristics, the population density at the origin and destination, the distance and time to the destination for several trip purposes, and access to public transit.

52274.基于二次型有界性理论的自适应巡航控制系统设计
[汽车制造业] [2014-03-19]
A new decision algorithm for ACC systems is proposed.Feasible driving set is defined based on state and control constraints,which represent driver behavior features.And based on the analysis of collected driving data,a second-order range policy is selected to approach real driver behavior.Under dynamic output feedback control framework,the decision algorithm has been developed based on quadratic boundedness theory and given in terms of linear matrix inequalities.Performance of the proposed algorithm is verified by Simulink and Carsim co-simulation.

52275.用户汽车选择模型研究报告
[汽车制造业] [2014-03-19]
As the model documentation states, While OMEGA incorporates functions which generally minimize the cost of meeting a specified carbon dioxide (CO2) target, it is not an economic simulation model which adjusts vehicle sales in response to the cost of the technology added to each vehicle. Because the OMEGA model does not presently estimate such impacts, the EPA is investigating the feasibility of developing an adjunct to the OMEGA model to make such estimates. This project is an effort to develop and test a candidate model. The project statement of work spells out the key functional requirements for the new model.

52276.汽车在火灾中生存性能改进研究
[汽车制造业] [2014-03-19]
The authors of this review have analyzed the auto industry reports, the scientific literature, and statistical data, and conclude that measures should be taken to improve survivability in automobile fires. The authors suggest that FMVSS 302 is no longer relevant to automobile fire safety and recommend improved standards based on objective criteria for fire safety performance (fireworthiness) at the system/vehicle level as is routinely done for crashworthiness.

52277.基于免疫PID控制的汽车防抱死制动系统控制算法研究
[汽车制造业] [2014-03-19]
A immune PID control algorithm based on classic PID is presented and used in automobile ABS system.Compared with the classic PID control algorithm and fuzzy control algorithm,the simulation result shows that the immune PID control algorithm has a shorter stabilization time,a smaller excess of system output,fewer response time and shorter braking distance,it is superior to the classic PID control algorithm and fuzzy control algorithm.The immune PID control algorithm has a higher application value.

52278.2014年1月汽车行业运行分析
[汽车制造业] [2014-03-18]
2014年1月，我国汽车产销保持增长势头，开局良好，当月销量再创月度新高。乘用车产销比上年同期呈现一定的增长，是拉动该月汽车增长的主要力量；商用车产销总体表现较为低迷。本月中国品牌乘用车销量、市场占有率环比同比均出现下降，小排量乘用车市场占有率环比小幅增长，但依然低于上年同期水平。1月我国汽车企业出口量继续呈现低迷局面，环比同比均出现下滑。全国汽车市场价格总体保持稳定，国产汽车与进口汽车价格均小幅走高。2013年，我国汽车行业经济运行平稳，重点企业（集团）主要经济指标稳步增长。

52279.2014年3月上半月汽车行业要闻综述
[汽车制造业] [2014-03-18]
中新网3月6日消息，近日，在2014汽车界“两会”代表委员座谈会上，工业和信息化部部长苗圩针对汽车界争论已久的“合资车企股比开放”话题做出表态。苗圩在3月4日晚的2014汽车界两会代表委员座谈会上表示，工信部所管辖范围内，如钢铁、化纤等，会分时段有序放开合资股比，汽车业会往后放一放。“放一放”具体是多久，苗圩并未在会上给出明确答案。工信部的态度表明，政府正在对于汽车业形成更为明确的国家战略。对于合资股比放开后自主品牌面临的竞争环境，苗圩言语中透露出很大的担忧：“时间是有限的，资源是有限的，不可能面面俱到；但自主品牌也必须尽快培养能与跨国公司竞争的能力。”对于建设汽车强国及其具体目标，苗圩表示，产销量并不重要，“2025年达到5000万辆也不能说明是汽车强国。要有一两家企业进入世界前几强、有一些技术能够引领全球汽车工业的发展，总要有局部领先。”苗圩进而引用张小虞的话表示“中国没有办不成的事情，关键是有明确的目标。要有路径战略选择，有所为有所不为。”
